Ensure the power is off before open the front Grill.
The air filter behind the front grille should be checked and cleaned
at least once every 2 weeks or more often if necessary.
The grille is designed to clean the filter downward.
To remove:
Open the inlet grille upward by pulling out the bottom of the
inlet grille. (Refer Fig. 1)
Using the tab, pull up slightly on the filter to release it and pull
it down (Fig. 1). Slide out five filter from grill (fig. 2).
Clean the filter with warm, soapy water below 40°C (104°F).
Rinse and gently shake the water from the filter and let it dry
before replacing it.
CAUTION:
DO NOT operate the air conditioner without a filter
because dirt and lint will clog it and reduce
performance.
Drainage
In humid weather, excess water may cause the BASE PAN to overflow.
To drain the water, remove the DRAIN CAP
To remove the condensed water, you can install the drain pan as below.
Take the drain pan which is located in the air discharge.
Install the drain pan to the right corner of the cabinet with 4 screws.
Connect the drain hose to the outlet located at the bottom of the drain
pan. You can purchase the drain hose or tubing locally to satisfy your
particular needs. (Drain hose is not supplied).

Long-off period maintenance
1)If the air conditioner is not going to be used for a long period, run the Air-conditioner with the
setting in FAN Mode only and the fan speed on "HIGH" for about half an hour, to dry the whole
Air-conditioner.
2)After a long off period when you are going to use the air conditioner again, repeat above point
no. 1.
There will possibly be foul smell when the machine is started after a long time (1 week). This is due
to various odours emitted by smoke, foodstuff, cosmetics and others, which sticks to the Air Filter
and Evaporator coil. Hence, clean the Air Filter and the Evaporator before you start the machine
after long time to avoid foul smell.
(Fig. 2)
-14-
Select the Best Location
To prevent vibration and noise, make sure the unit is installed securely and firmly.
Install the unit where the sunlight does not shine directly on the unit.
There should be no obstacle, such as a fence or wall, within 1000mm from the back of the cabinet because it will prevent
heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.
Install the unit a little obliquely outward not to leak the condensed water into the room (about 10 ~ 15mm or 1/4
bubble with level).
CAUTION:
All side louvers of the cabinet must remain exposed to the outside of the structure.
Remove the Air Conditioner From the Case
Remove the 2 shipping screws from the
back of the case.
Remove the 2 screws on each side of the
case. Keep these for later use.
Slide the air conditioner from the case by
gripping the base pan handle and pulling
forward while bracing the case.

10 Easy Steps to find out your AC tonnage
Dear Customer,
Please follow Below mentioned 10 easy steps to find out the AC tonnage required for your room.
Example : For Room size 15 feet(L) x 12 feet(B) x 10 feet(H) with one window 4 feet x 3 feet exposed to
sun (west) & one wall exposed to sun (east).The room is on First floor with ceiling not exposed to sun.
The no. of persons occupying the room is 4 nos. The appliance load is 2 tube lights, 1 Computer & 1 TV.
Calculate the AC tonnage required.
As per steps given above : room volume : 15*12*10 = 1800 cu. Ft. , window area = 4*3=12 sq.ft.,
Wall area (east) = 15*10=150
Step1 = 3 Step6 = 2
Step2 = 2 Step7 = 2
Step3 = 0 Step8 = 0
Step4 = 0 Step9 = 1
Step5 = 1 Step10= 3

IMPORTANT: Long term effect not tested and mosquitoes may become resistant. Mosquito species used in the
test below may differ from the mosquito species of your region. This product is one of the ways to manage
mosquitoes and not intended to replace other protective devices against mosquitoes.
DISCLAIMER
Test Details:
A: Tested by International Institute of Biotechnology and Toxicology (IIBAT), India, According to LG internal
testing method.
Test conducted, three times at temperature of 27±2°C and humidity of 60±10%
Test used two chambers size 3.5m x 2.6m x 2.2m, the chamber with the LG air conditioner assumed to be
inside (“inside chamber”) and the chamber without the LG conditioner assumed to be outside
(“outside chamber”).
3
Cages (25cm ) are placed inside each chamber, connected using netted sleeves to enable the movement
of the mosquitoes from one cage to another.
One person is placed inside the chamber to attract mosquitoes
For each test, 50 lab cultured 3-5 days old mosquitoes were placed in the cage in outside chamber; number
of mosquitoes coming into the cage in inside chamber was counted every 10 minutes for 90 minutes under
2 settings:
Control setting (low fan ON + mosquito repelling ultrasonic OFF)
Treatment setting (low fan ON + mosquito repelling ultrasonic ON)
Test Result:
Found to repel on average 81.1% of Aedes aegypti mosquitoes. Repel rate shows percentage of mosquitoes
prevented from entering the inside chamber after 90 minutes of Treatment setting compared to Control setting.
Represented average of 81.1% derived from 76.9%, 84.6%, 81.8%.
B: Tested by Intertek, Korea,
According to LG internal testing method.
Test conducted, three times at temperature of 27±2°C and humidity of 60±10%
3 3
Test used two chambers size 33m and 19m connected by a channel made of white sheet, small
chamber assumed to be outside (“outside chamber”) and the large chamber to be inside with the
LG air conditioner (“inside chamber”)
One person is placed inside the inside chamber to attract mosquitoes
For each test, 50 lab cultured 3-5 days old mosquitoes were released into outside chamber; number of
mosquitoes coming into the inside chamber was counted every 10 minutes for 90 minutes under 2 settings:
Control setting (low fan ON + mosquito repelling ultrasonic OFF)
Treatment setting (low fan ON + mosquito repelling ultrasonic ON)
Found to repel on average 72.5% of Aedes aegypti mosquitoes. Repel rate shows percentage of mosquitoes
prevented from entering the inside chamber after 90 minutes of Treatment setting compared to Control setting.
Represented average of 72.5% derived from 73.1%, 64.3%, 80.0%.
Test Result:
Results may vary in other settings, including but not limited to temperature, humidity, location, space, mosquito
species, number of mosquitoes, number of persons, and operation time.
